To "The Dude". It is not just a filter. This is from their website from the 211+ Auto page. "Blueair air purifiers use HEPASilent™ dual filtration technology, delivering maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration." Electrostatic charging sounds like more than a just a filter to me. I returned mine because of this.
Sorry, there was a problem. Please try again later.Hi Jeff, Blueair has conducted ongoing independent testing to ensure our air purifiers do not release harmful levels of ozone. All Blueair air purifiers are tested in accordance with UL Standard 867, demonstrating ozone emission levels far below the mandated California Air Resource Board (CARB) ozone emissions limit of less than 50 parts per billion (ppb). All Blueair air purifiers are CARB certified.
